My 95" screen is 15 years old and I've never ever felt the urge to replace it.
Right now I'm still on 1080P. Perhaps when I upgrade to a true 4K projector I might feel differently, but for right now it's fine.
Did I mention it was free with my first Optoma projector and the list price was just $90?
The only reason I could think of of getting a more expensive one otherwise is if it had a motorized retractor. That said, my current one has been fully extended almost 100% of its life...
Not sure it is a Benq HT3550
More expensive in relation to what? $100 vs $200 vs $1.000 vs $10.000? And what is "better"? Are you looking for a screen that improves your black level? Brightness? Viewing angle? Color uniformity? Reject ambient light? General build quality? Better tensioning? More masking options? Or maybe an acoustically transparent screen? Wooven or perforated? What's the viewing distance, how big can the perforation be? What speakers would you put behind the screen, that might limit your choices too. What resolution, etc.?
I've used screens from under $100 (including screen paint) to over $20k. Size is major factor in price as well. So what are you trying to accomplish?
Also the HT3550 isn't a true 4k projector. There are no native 4k consumer DLP chips or LCD panels. If you want native 4k cheap, then it's Sony or JVC. Otherwise it's more expensive, more light output, much bigger, noisier and hotter, so you better put those in a projection booth or custom (temperature controlled) hush box with glass sealing.
For better tensioning, better build quality is a must. So if you're looking for better tensioning, yes, it is absolutely worth it. The more expensive screens usually stay properly tensioned and flat in comparison to something cheaper. It can also depend on temperature and humidity. For tensioning the quality of the projector does not matter, it's a screen issue.Better tensioning .
Viewing distance 8 to 10 ft.
Would it be worth it for a projector like my BenQ HT3550 ?
